Vincent Liu

I’m a senior software engineer with 6+ years of experience designing carrier-grade API services and scalable distributed systems. I’ve delivered proven expertise in Golang, Node.js, and Java, with production experience across healthcare and telecommunications domains.

I lead multi-cloud migration initiatives and build geo-redundant, high-availability systems handling millions of daily transactions. In recent work, I architected and deployed APIs processing 5M+ daily requests on EKS, achieving 99.99% uptime for telecommunications clients.

I focus on reliability, performance, and operational excellence—optimizing latency and costs through engineering fundamentals like query tuning, caching, and rate limiting. I reduced service reliability MTTR from 45 to 12 minutes, cut latency by 35%, and reduced infrastructure costs by 28% while delivering zero-downtime CI/CD.

I’m also product-focused and security-minded, passionate about developing trusted digital identities and combating fraud. I’ve implemented OAuth2/JWT authentication, delivered HIPAA-aligned encryption and monitoring, and supported security audit remediation leading to SOC 2 Type II certification for API services.
